Drinking water for dry mouth does not work, but we need to analyze the specific problem. Due to the deficiency of fluid or sweating after exercise, the body’s fluid deficit is less, when the dry mouth and dry tongue drink water does not work. If there is dry mouth, drink water does not work, to be divided into the following two cases. The first situation, the body has phlegm drink. In particular, the spleen and stomach ability to transport water and dampness is reduced, phlegm drink, resulting in the uneven distribution of water, this time appear dry mouth, but drink water does not work, only the more water you drink, the more obvious the symptoms of dry mouth. Because water, as a liquid, also causes internally generated phlegm, which affects the transportation and transformation of the spleen and stomach. At this time, we need to transport water-dampness and strengthen the spleen and stomach. As long as the transport ability of water-dampness is strengthened after the spleen and stomach are powerful, the phlegm drink will disappear and this dry mouth symptom will be alleviated. The second condition, blood stasis. Blood stasis will also hinder the operation of qi and blood leading to uneven distribution of water and fluid, which is accompanied by dry skin, pain or insomnia, forgetfulness and other symptoms.
